Stream1 and Stream2
There are two streams running concurrently: Stream 1 and Stream 2. By default, Stream 1 has the higher resolution than stream 2.
Stream 2 serves lower resolution for mobile devices which has smaller screens. Each stream has independent settings.
Compression Format: H.264 is suggested that serves the best
compression quality.
Resolution: This sets the resolution of the image. Higher
resolution delivers higher quality image but consumes more
storage spaces and network bandwidth.
Max. Frame per Second: This sets the maximun number of frames
to be captured per second. Higher frame rate delivers smoother
video but consumes more storage spaces and network bandwidth.
Bit Rate Encoding: This sets the bit rate encoding at which tha
output data consumed is constant or variable per time segment.
Bit Rate (Ethernet): The bit rate when data is transmitted using
Ethernet.
Bit Rate (WiFi): The bit rate when data is transmitted using
wireless connection.
You are adivsed to set a smaller video size and lower bit rate for remote viewing on mobile phones (Stream 2) and a larger video size
and a higher bit rate for live viewing on web browsers (Stream 1). In addition, Ethernet suffers less interference and tends to be faster
than wireless; therefore, the bit rate can be set higher for (Stream 1). The reason that Stream 2 bit rate settings are both low simply
because Stream 2 is applied to serve low bandwidth appliances such as mobile phone.
